WRINGER ATTACHMENT FOR TUBS.

Application filed September 5, 1919.

following to be a full, clear, and eXact description of the invention,such as will enable others skilled in the art to which it ap pertains tomake and use the same.

This invention relates to clothes wringing attachments for wash tubs andit has for its object to provide an article about which may be passedthe fabric to be wrung and which will hold securely to the usual sheetmetal wash tub, against the strains that are incident to the wringingoperation.

A further object of the invention is to provide a construction that willbe extremely simple and correspondingly cheap of manufacture and whichwhile holding tightly in use, may nevertheless be easily and quicklyremoved and as readily applied.

In the drawings:

Figure 1 is a perspective view showing the article in use upon a tub.

Fig. 2 is an enlarged perspective view of the attachment, a portion of awall of a wash tub being shown in sectional perspective to illustratethe manner in which the peculiar U-shaped clamp serves not only tofasten the attachment to the tub wall, but also to prevent rocking ofthe attachment upon loosening of the clamping screw and other annoyancesdue to the violent wrenchings to which an attachment of this characteris ordinarily subjected.

Fig. 3 is a transverse section on line 3-3 of Fig. 2. 7

Referring now to the drawings, the present attachment comprises a hookmade of a rod or bar of metal that is bent to form the bill 5, the shank7 and the connecting bend 6. The shank stands horizontal, and at its endit is herein shown as bent at right angles away from the bill but in thesame plane with the remainder of the hook and it is flattened at itsside remote from the bend of the hook to lie snugly against the innerarm 8 of a U-shaped clamp which includes also the outer arm 9 and thecurved or bent intermediate stem 10, this flattened portion of the hookbeing shown at 11 and being secured to the inner arm of the clamp byrivet v12- Specification of Letters Patent.

Serial No. 321,843.

The spacing of the arms of the clamp is slightly more than thethicknessof the head 13 that is formed by bending outward over a wire the upperedge of the usual sheet metal wash tub 14. Through the outer arm 9 isformed a threaded perforation 15 with which is engaged a thumb screw 16,the head 17 of which is disposed outwardly. The inner end of the thumbscrew 16 is reduced in diameter and swiveled as shown at 18 in aperforation formed centrally through a U-shaped plate or clamping jaw 20which is disposed between the arms 8 and 9 the parallel outturned endportions 21 and 22 snugly but slidably engaging the parallel side edgesof the outer arm 9. The perforation is countersunken so that theextremity 19 of the thumb screw may be upset thereinto, thus topivotally connect the thumb screw with the movable clampin jaw thatcooperates with the inner arm 8 which forms the opposing jaw.

By reason of the ends 21 and 22 lying snugly against the side edges ofthe arm 9, this jaw 20 is prevented from oscillating on the thumb screw.By reference to Fig. 2 of the drawings, it will be noted that the jaw 20is so positioned with respect to the bend 10 of the clamp, that when thelatter is engaged over the beaded upper edge of the wash tub and thethumb screw is operated to force the jaw 20 against the outer surface ofthe tub, said jaw will enter snugly beneath the bead 13 and thus willnot only serve to prevent upward withdrawal of the attachment from thetub, but will prevent rocking of the clamp on the tub, with the sameefiiciency as if a plurality of set screws were employed and thus willthe hook be held in proper position at all times. Furthermore, with thisconstruction an extended bearing surface is provided between the outerwall of the tub and the movable clamping plate, which latter may beinitially bowed on a shorter radius than that of the tub, as indicatedin dotted lines in Fig. 3, so that it will be flattened or spread to thecurvature of the tub wall when the thumb screw is operated and thus willhold the thumb screw more securely from unscrewing. Finally, twisting ofthe attachment under the strain of wringing and its eventual dislodgmentfrom the tub, as well as buckling of the wall thereof, are avoided bythe construction described. The jaw closely underlies the bead and notonly holds the clamp to the tub wall but holds it down upon the beadthereof, and the inner arm of the clamp is elongated so as to have amplebearing against the inner face of the tub wall from its bead for quite adistance downward. The depending right angular stem of the hook isriveted to this arm of the clamp, so that both are strengthened and theshank of the hook is rigidly sustained in horizontal position,projecting inward over the tub from a point about flush with the bend ofthe clamp.

What is claimed is:

A wringer attachment comprising a clamp including an inverted U-shapedbody for engagement over the beaded upper edge of a wash tub, a U-shapedclamping jaw disposed between the arms of the body below its bend withits ends outturned and slidably embracing the side edges of the outerarm, means for adjusting the jaw toward and away from the inner arm, anda hook carried rigidly by such inner arm to receive an article to bewrung.

In testimony whereof I aflix my signa ture in the presence of twowitnesses.
